  • A date filter restricts data to a specific time period in queries or reports.
    It is common because most business metrics are time-based.
    In my project, we filtered sales by month, quarter, or year for reporting.
    Date filters help track trends, compare periods, and measure performance.
    They improve query efficiency by reducing the dataset size.
    Common operators include =, <, >, BETWEEN, and functions like DATEPART.
    Using date filters ensures reports reflect the relevant time frame.
